【摘要】 在Tamura M.,Okada及廖亮研究的基础上,通过禺毛茛复合体(禺毛茛R.cantoniensis 4x,卷喙毛茛R.sileri folius var.silerifolius 2x,长花毛茛R.sileri folius var.dolicathus 2x,茴茴蒜R.chinensis 2x,扬子毛茛R.sieboldii 6x及8x)的核型分析,结合地球环境的演变历史,进一步研究了禺毛茛的形成方式和时间,并对禺毛茛复合体种间亲缘关系的形成进行了探讨,为毛茛属系统进化研究提供资料。更多还原

【Abstract】 The karyotypes of R.cantoniensis,R.silerifolius var.sileri-folius,R.silerifolius var.dolicathus,R.chinensis and R.sieboldiiin R.cantoniensis complex were studied by means of the cytological observation of root-tips on the basis of previous studies.In combination with the history which earth evolved,the forming way and time of R.cantoniensis was further studied,and the forming mechanism of inter-specific relation in R.cantoniensis complex was discussed so as to offer more data for the study of phylogenetic and evolution in genus Ranunculus.更多还原
